Online or Offline Configuration
Devices can be configured before or after
installation on a properly-terminated serial bus. If
a new device is to be added to an existing bus
running at a baud rate other than 153.6 Kbaud
standard, the device must first be configured
offline. Be careful adding new devices to existing
systems. Be sure the baud rate configured for the
new device matches that of the system - never mix
baud rates on a bus.
Online Configuration
When configuring a device on an operating bus,
the Hand-held Monitor must be the ONLY HHM
plugged into a device on the bus. If devices are
configured online, the HHM automatically check
for PLC reference address conflicts.
Offline Configuration
It may be most convenient to configure devices
off-line at a central location. Each device will need
to be connected to an appropriate source of power
and to earth ground. To prepare a device for
off-line configuration:
1. Connect a 75 ohm resistor across the Serial 1
and Serial 2 terminals, or use the 75 ohm
terminator plug (IC660BLM508).
2. Attach a grounding strap to the device’s
ground screw. Be sure that the strap is
connected to earth ground.

3. Wire the device to the power source and apply
power.
Warnings
If the device is not properly grounded,
hazardous voltages may exist. Death or
injury may result.
DO NOT TOUCH the connectors or
wiring after powering up the device.
Hazardous voltages exist, and death or
injury may result.
Starting Configuration
Note: To assign a serial bus address, the
Hand-held Monitor must be directly attached to
the device being configured. Additional features
can be configured with the Hand-held Monitor
connected at any point on the bus. In that case, the
device being configured must be selected as the
active device (on the Block/Bus Status screen).
1. Begin with the Hand-held Monitor turned off.
Attach the HHM to the device (see below) or
to another bus connection point.

2. Turn the Hand-held Monitor on. After the
HHM completes its powerup sequence, the
Home menu appears. The Hand-held
Monitor’s Change Block Configuration option
must be enabled to complete the instructions
in this section. For a new device, the HHM’s
Change Block ID and Change Block Baud
options must also be enabled.
